Risk Overview
Overall natural disaster risk in Crockett County is low, with a National Risk Index score of 52.6 out of 100 — placing it in the 53rd national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Most of Crockett County's expected losses come from earthquake (ground shaking from sudden movement along geologic faults) at Medium risk — $7M in expected annual loss and about 0.01 events per year; ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $153K in expected annual loss and about 1.19 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $606K in expected annual loss and about 1.81 events per year. Across all hazards, FEMA estimates $13M in expected annual loss for a population of 14K.
Beyond physical exposure, Crockett County has a very high social vulnerability rating (how susceptible the population is to harm) and a medium community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
The federal record bears this out: Crockett County has received 19 federal disaster declarations since 1979, including 14 for severe storm events and 2 for winter storm events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.
Among 95 Tennessee counties, Crockett County ranks #52 for overall natural disaster risk.
